This invention relates in general to trans port mechanisms and moreparticularly has reference to a combination elevator conveyor.

Previous to this time there has not been provided any mechanism adaptedto transport material from various points or from one elevation toanother where the points of loading and the points of discharge arecontinuously changing in their relation to each to other.

An object of this invention is to provide a combination elevator andconveyer adapted to transport material from various points.

Another object of this invention is to provide a combination elevatorand conveyer adapted to transport material from one elevation toanother.

A further object of this invention is to provide a combination elevatorand conveyer 2e adapted to transport material from various points, orfrom one elevation to another where the pointsof loading and the pointsof discharge are continuously changing in their relation to each other.

This invention consists in general of the provision of a transportdevice comprising a series of interchangeable units which may becombined to form various combinations of conveyors and elevators of anydesired length.

With these and other objects in View which may be incident to myimprovements, the invention consists in the parts and combina tions tobe hereinafter set forth and claimed, withthe understandingthat theseveral necessary elements comprising my invention may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order to make my invention more clear- 1y understood, I have shown inthe accompanying drawings means for carrying the same into practicaleffect, without limiting the improvements in their useful applicationsto the particular constructions, which for the purpose of explanation,have been made the subject of illustration.

In the drawings:

Figure 6 is an elevational view showing an adjacent end of conveyersection.

Fig. 7 is a sectional view taken on line 5-5 of Figure 4;

Fig. 8 is a front view section.

Referring by numerals to the drawings, wherein like symbols of referencerefer to similar elements throughout and more particularly to Figure 1,the combination elevator and conveyor comprises a driving ordischarging-section 1, a power section 2, a return section 8, and a bodyor filler section 4:.

The various sections comprising the combination elevator and conveyorare joined by a connection 5, illustrated in greater detail in Figures4, 5 and 6 to behereinafter more fully described. The sides of thesections forming the conveyor frame are made up of oppositely disposedaligned channel irons 6 and 7 as shown in Figure 7. A plate 11 iscentrally fixed to the inner surfaces of the channel irons 6 and 7 andfastened by angle irons 13 and 1 1 or by any other suitable means.

The ends of a shaft 15 are journaled in the frame on the end of thedischarging section 1, as shown in Figure 8, and held therein by collars16 and 17. A sprocket wheel 18 is key-ed to the end of the shaftprojecting through the collar 16. There are also keyed on the shaft,sprocket wheels 19 and 21.

The ends of a shaft 22 are journaled in the end of the frame on thereturn section 8, as shown in Figure 1, and held by collars 23 and 24.There are also mounted on the shaft, sprocket wheels 25 and 26 inalignment with the sprocket wheels 19 and 21 keyed on the shaft 15.

05 of the discharge The power section 2 is mounted on a base 27 togetherwith a motor 28. The motor 28 may be of any desired type deemed mostsuitable for the particular requirements and may be located at any pointdesired as it is manifest that a particular mounting of the source ofpower is in no wise a necessary feature of this invention.

The motor 28 is provided with a drive shaft 29 having keyed thereon asprocket wheel 31. Mounted parallel to the drive shaft 29 of the motoris a shaft 32 supported by standards 33 mounted on the base 27. Asprocket wheel 34 is keyed on one end of the shaft 32 and anothersprocket 35 is keyed on the other end, as shown in Figure 1.

The adjacent sections of the mechanism are joined by a connection 5,better shown in Figure 4 wherein the longitudinal sections through theopen joint shown in F igures 5 and 6 show the details of the connection.

A splice plate 36 formed as a channel iron is riveted to the section 4or secured by any other suitable means through apertures 32. The otherend of the splice plate 36 is provided with apertures adapted tocoincide with slotted apertures 39 bored in the end of the adjacentsection 1, and secured thereto by bolts 41. The slotted form of theapertures 39 permits longitudinal adjustment of the sections.

Plates 42 are fixed to the top and bottom of the channel irons formingthe frame on one end of each section to be joined and the adjacentsection is slipped in between the plates. A plurality of blocks 43 aremounted on each section between the opposite ends of the plates 42 andfixed therein by bolts 44.

The connection is tightened after two adjacent sections have beenproperly drawn in position by takeup bolts 45 having heads 46 and nuts47 extending through the blocks 43.

The plates 11 of the adjacent sections are beveled at their ends sothat, when two sections are drawn together by the bolts 45 and fixed inplace by the bolts 41, smooth running surface will be presented. Asupplementary plate 48 is fastened beneath the beveled connections ofthe plate 11 to prevent leakage at these points.

Flanges 51 are mounted on the top of the frame to prevent spillage ofmaterial during operation. At the point of juncture of adjacent sectionsa supplementary flange 52, having an indented bottom portion, isinsorted to clear the top plate 42 forming the connection 5 and engagethe 'iange on the adjacent section. T he flanges may be dispensed withif so desired.

A flexible transmiss on mechanism 53, such as a steel chain, comprPsinnks and ers 55, is adapted to or e the "'1 sprockets 19 and 21 keye onti on the forward section 1, and the s 1a sprockets 25 and 26 keyed onthe shaft 22 on the return section 3. Transverse cross flights 56,having end portions 57, are mounted on the chain 53, adapted to slide onthe plate 11. The cross flights 56 are suitably spaced to afford thegreatest utility for the particular material being conveyed.

A suitable flexible transmission mechanism such as a chain 58 is adaptedto cooperate with the sprocket wheel 31 keyed on the shaft 29 on theprime mover 2S, and the sprocket wheel 34 keyed on the shaft 32 on thedriving section 2, as shown in Figure 2. A like chain 59 is adapted tocooperate with the sprocket wheel 35 keyed on the opposite end of theshaft 32 and the sprocket wheel 18 keyed on the shaft 15 in the end ofthe frame on the forward portion 1.

The prime mover 28, through this series of sprockets and chains, isadapted to operate the head shaft 15 and the driving sprockets 19 and 21keyed on the shaft, which in turn operate the chain belts 53 rotating onthe sprockets 25 and 26 keyed on the shaft 22. thus operating the crossflights 56 and affording forward or backward carriage of any materialdeposited on the plate 11.

The chains are adapted to be detachable or separable at suitable pointsso that they may be lengthened or shortened to accommodate the sections1, 2 and 3 and the total of body sections 4 employed to make up acomplete unit. The chain 59 is also separable and extensible orretractable so that it may be adjusted to suit any desired distancebetween the sprockets 18 and according to the number of body sections 4used.

The operation of this invention may be readily understood hay ingreference to F igures 2 and 3. The form of the mechanism is dependentupon the position of the body or filler sections 4 with respect to thedriving and discharge sections 1 and 2. Vhen the section 4 is insertedbetween the sections 1 and 2 the assembled unit is adapted to functionas an elevator, as shown in Figure 2. to elevate material to a car 61 orany other receptacle, or if it is desired that the mechanism serve forlongitudinal transport, the sections 4 are inserted between the powersection 2 and the return section 3, and assembled in this form functionsprimarily as a conveyer with only a slight elevation at the end wherethe material transported may be discharged into a chute 62 or anysuitable conveyer.

It is apparent that the assembled unit may be extended by insertingadditional sections 4 up to the limit of the power of the prime mover 28and the resistance of the chains 53 forming the conveying or elevatingdrive.

There is accomplished by this invention a combination elevator andconveyer having a series of separable interchangeable units adapted tobe combined to form various combinations of conveyers and elevators toafiord eficient transport for materials where the point of loading andthe point of discharging are continuously changing in their relation toeach other.

While I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not confine myself tothe precise details of construction herein set forth, by way ofillustration, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention, or exceeding the scope of the appended claims.
